Preparation Guide by American Board of Health Physics PREPARATION GUIDE BY AMERICAN BOARD OF HEALTH PHYSICS PROFESSIONAL RESPONSIBILITIES OF HEALTH PHYSICISTS CERTIFIED BY THE AMERICAN BOARD OF HEALTH PHYSICS In achieving certification, the Certified Health Physicist recognizes and assumes the responsibilities due the profession of health physics. To uphold the professional integrity of health physics implied by certification, the relations of the Certified Health Physicist with other individuals and groups including clients, colleagues, governmental agencies, and the general public shall always be based upon and reflect the highest standards of professional ethics and integrity. Each certificant has a professional and ethical obligation to practice only in those areas of health physics in which he or she is competent. To maintain technical competence, the Certified Health Physicist has a commitment to remain professionally active in the field of health physics and knowledgeable of scientific, technical and regulatory developments in the field. The American Board of Health Physics offers Comprehensive Certification in Health Physics. The certification examinations are normally given once a year at the time of the Annual Meeting of the Health Physics Society. They are held at the location of the Society's meeting and at other selected locations where the demand warrants. Information regarding requirements for Certification, examination procedures and fees, and application materials are available on this website. Additional information is available from: Amy Wride-Graney, Program Director American Board of Health Physics 1313 Dolley Madison Boulevard, Suite 402 McLean, VA 22101 (703) 790-1745 FAX: (703) 790-2672 Email: [email protected] Webpage: http://www.aahp-abhp.org/ Caution - The information presented about the exam specifics and other matters are believed to be correct at the time of preparation; however, the Board has revised the procedures and criteria in the past, and reserves the right to do so in the future. The candidate is advised to review the current copy of the ABHP Prospectus for the current policy. Section 1 Message to Candidates This guide will help you prepare for the ABHP certification examination. However, use of the Guide by itself will not be adequate preparation for the exam. Successful candidates usually start their preparation months before the test. Preparation should include a careful review of health physics fundamentals and then, with equal vigor, review of applied aspects of health physics in several of the specialty areas. The suggested study references in Section 7 will help guide you. Joining either a formal or informal study group (particularly those that continue over a period of months) can assist you by forcing a systematic review of various topics and by exposing you to the knowledge of people expert in subjects with which you are not familiar. The Board warns against approaching the exam in a casual fashion. We find that most unsuccessful candidates did not prepare adequately. In contrast, the successful candidates have usually planned and followed a comprehensive study program. After past exams, the Board has asked candidates about some of the factors contributing to their degree of success on the exam. The Board noticed that the single most important attribute of successful candidates was the amount of time spent studying for the examination. On average, those questioned claimed to have spent an average of 300 hours in study. Because candidates' credentials are reviewed carefully, the Board feels that all applicants declared eligible to take the examination have the potential to pass. You can avoid the disappointment of poor performance by recognizing from the start that the exam will be a rigorous test of your professional knowledge. Your grade will represent, for the most part, the thoroughness of your preparation. Section 2 Exam Locations The certification examinations are given one day each year. The exam is given at the site of the annual meeting of the Health Physics Society and, on the same day, at several other locations throughout the country. The exam sites for each year will be selected by the American Academy of Health Physics' Examination Site Selection Committee by February 1 of each year. All approved candidates will be sent a site selection survey form in early March listing the tentative examination sites. The candidate should indicate first and second choices of location and will be assigned to the first choice unless that site does not have enough candidates to warrant the examination being given there. All candidates will be notified of their definite exam site approximately 45 days prior to the examination date. Exam Scheduling Once a candidate is notified of eligibility to take an examination, the candidate is expected to appear at the next scheduled examination. Examination fees are non-refundable. Application material is only good for a two year period and must be resubmitted after two years. A candidate who is scheduled to take an exam may postpone it up to the moment before the exams are distributed. Once a candidate has received an exam, it must be submitted for scoring. Should the ABHP make policy changes that could affect a candidate's eligibility to take the exam once a candidate has been declared eligible by the admissions process, a candidate will remain eligible for the full period of initial qualification. Re-examinations After paying the exam fee, a candidate who fails the first examination may be admitted to the next examination without resubmitting an application if it is within two years of the application date. An application is only good for two years (two exam cycles). If a candidate passes one part of the exam, the candidate must pass the other part within a period of seven years, or must reapply and retake both parts. The candidate must notify the Board of his/her intention to retake the examination and submit the proper fee no later than January 15 of the year in which the examination is to be taken. Section 3 The examination has two parts. Calculators may be used during the exam. No recording or transmitting devices are permitted, and all calculators with "constant" memories must be demonstrated to contain no stored constants (other than pi or e) or stored programs. Part I Part I questions are used to evaluate a candidate's knowledge of the fundamentals of health physics. Part I is made up of 150 multiple-choice questions. The breakdown by subject matter follows the five Domains of Practice which are detailed in Section 4. The sub-areas shown for each domain give the typical subject matter covered in Part I questions. The number of Part I questions which fall in each domain is also shown in that section. Part I of the examination is constructed to test the knowledge of the fundamental aspects of health physics that is expected of any candidate meeting the qualifications for early admission to Part I. There will be questions contained in Part I that address fundamental knowledge associated with applied health physics. Academic preparation alone may not be adequate to answer these questions. However, the presence of these questions should not prevent a well-prepared candidate with no practical experience from successfully completing Part I of the Certification examination. Each question has five possible answers from which to choose and requires thorough knowledge of the subject matter. For example, in questions that require calculations, answers other than the correct one are obtained by making some of the common calculational errors. Three hours are allowed to answer Part I (given in the morning of the examination day). Part I questions may be reused in subsequent years. As a consequence, this part of the examination is held in strict confidence and copies of past exams are not distributed. Section 8 of this Guide gives some typical Part I questions. Part II Part II questions are designed to test judgment, the ability to analyze and organize complex problems, and the use of practical skills at a high professional level. Candidates are given six hours in which to complete Part II (given in the afternoon of the examination day). In the first section of the Part II exam, there are six questions on core topics of health physics. These first six questions will be graded for all candidates. (If one of these questions is left unanswered, the candidate will receive zero points for that question.) The topic areas that these questions examine are: personnel dosimetry (internal and external), shielding and activation, measurements and instrumentation, and biological effects of radiation (risk). These questions are selected so that each can be read and answered in a period of 10-15 minutes. Each question is worth 50 points and can include calculations, short essay, and/or serial-multiple-choice format. The second section of the Part II exam contains eight problems. These problems are provided in one or a combination of the following formats: essay, short answer, calculational, serial-multiple-choice. The candidate must select any four of the eight questions provided. At least one question is provided for each of the following topical areas: Accelerators Environmental Fuel Cycle (mining, milling, fuel fabrication and fuel reprocessing) and waste management Medical Research and Power Reactors University General (can include emergency response, meteorology, standards and regulations, and topical subjects) Nonionizing Each question from a topical area is designed such that a candidate who is experienced and capable in that area should be able to answer the question. However, all questions are kept general enough so that a person without detailed experience in an area, but who has adequately studied that area, could answer with a reasonable likelihood of success. Each question in the second section is designed to be read and answered in about 30 minutes and is worth 100 points. Part II Subject Matter In addition to the criteria noted above, the Part II questions are selected by subject matter to meet the percentage breakdown associated with the five Domains of Practice which are detailed in Section 4.

  • Radiation Risk in Perspective
    PS010-1 RADIATION RISK IN PERSPECTIVE POSITION STATEMENT OF THE HEALTH HEALTH PHYSICS SOCIETY* PHYSICS SOCIETY Adopted: January 1996 Revised: August 2004 Contact: Richard J. Burk, Jr. Executive Secretary Health Physics Society Telephone: 703-790-1745 Fax: 703-790-2672 Email: [email protected] http://www.hps.org In accordance with current knowledge of radiation health risks, the Health Physics Society recommends against quantitative estimation of health risks below an individual dose of 5 rem1 in one year or a lifetime dose of 10 rem above that received from natural sources. Doses from natural background radiation in the United States average about 0.3 rem per year. A dose of 5 rem will be accumulated in the first 17 years of life and about 25 rem in a lifetime of 80 years. Estimation of health risk associated with radiation doses that are of similar magnitude as those received from natural sources should be strictly qualitative and encompass a range of hypothetical health outcomes, including the possibility of no adverse health effects at such low levels. There is substantial and convincing scientific evidence for health risks following high-dose exposures. However, below 5–10 rem (which includes occupational and environmental exposures), risks of health effects are either too small to be observed or are nonexistent. In part because of the insurmountable intrinsic and methodological difficulties in determining if the health effects that are demonstrated at high radiation doses are also present at low doses, current radiation protection standards and practices are based on the premise that any radiation dose, no matter how small, may result in detrimental health effects, such as cancer and hereditary genetic damage.

  • Recommendations for the Follow-Up Assessment of Contaminated Travelers by Radiation Control Health Physics Staff
    Recommendations for the Follow-Up Assessment of Contaminated Travelers by Radiation Control Health Physics Staff State radiation control program health physicists will perform the follow-up assessment of contaminated travelers in coordination with the local or state health department. This assessment may be done at the state radiation control program office, the traveler’s place of residence, or other locations as convenient. This screening process may be stressful for travelers. The health physics staff should consider requesting assistance from behavioral health professionals or risk communicators to help reduce anxiety for travelers throughout the process. The follow-up assessment should consist of four main activities: 1) Ensure the effectiveness of external decontamination 2) Assist in completion and review the Epidemiologic Assessment form with the traveler and assess potential for internal contamination 3) Perform a thyroid count 4) Evaluate the need for bioassay, and collect a urine sample if necessary Based on current environmental monitoring results reported from Japan, it is highly unlikely for any external or internal contamination to present a public health concern for people outside of the 50-mile (80-kilometer) radius around the Fukushima nuclear power plant. 1) Ensure the effectiveness of external decontamination Travelers identified as being contaminated with radioactive materials by U.S. Customs and Border Protection (CBP) are offered an opportunity – at the airport – to change into clean clothes and wash exposed skin surfaces, such as their hands and face. Additional washing (such as a full shower) may be necessary to remove all traces of external contamination. The effectiveness of external decontamination performed by the traveler at the airport or at home can be verified using a beta/gamma radiation detection instrument such as a Geiger Muller (GM) pancake probe or equivalent.

Asbestos is the name given to a group of naturally occurring minerals used in certain Equipment products, such as building materials and vehicle brakes, to resist heat and corrosion. Clearance Asbestos includes chrysotile, amosite, crocidolite, tremolite asbestos, anthophyllite for asbestos, actinolite asbestos, and any of these materials that have been chemically 2 Disposal treated and/or altered. or What are the dangers of asbestos exposure to workers? Relocation The inhalation of asbestos fibers by workers can cause serious diseases of the lungs and other organs that may not appear until years after the exposure has occurred. For Biosafety instance, asbestosis can cause a buildup of scar‐like tissue in the lungs and result in Bulletin: loss of lung function that often progresses to disability and death. Asbestos fibers Risk associated with these health risks are too small to be seen with the naked eye, and smokers are at higher risk of developing some asbestos‐related diseases.

  • Internal and External Exposure Exposure Routes 2.1
    Exposure Routes Internal and External Exposure Exposure Routes 2.1 External exposure Internal exposure Body surface From outer space contamination and the sun Inhalation Suspended matters Food and drink consumption From a radiation Lungs generator Radio‐ pharmaceuticals Wound Buildings Ground Radiation coming from outside the body Radiation emitted within the body Radioactive The body is equally exposed to radiation in both cases. materials "Radiation exposure" refers to the situation where the body is in the presence of radiation. There are two types of radiation exposure, "internal exposure" and "external exposure." External exposure means to receive radiation that comes from radioactive materials existing on the ground, suspended in the air, or attached to clothes or the surface of the body (p.25 of Vol. 1, "External Exposure and Skin"). Conversely, internal exposure is caused (i) when a person has a meal and takes in radioactive materials in the food or drink (ingestion); (ii) when a person breathes in radioactive materials in the air (inhalation); (iii) when radioactive materials are absorbed through the skin (percutaneous absorption); (iv) when radioactive materials enter the body from a wound (wound contamination); and (v) when radiopharmaceuticals containing radioactive materials are administered for the purpose of medical treatment. Once radioactive materials enter the body, the body will continue to be exposed to radiation until the radioactive materials are excreted in the urine or feces (biological half-life) or as the radioactivity weakens over time (p.26 of Vol. 1, "Internal Exposure"). The difference between internal exposure and external exposure lies in whether the source that emits radiation is inside or outside the body.
